Stainless Steel Chain has many advantages.
•
It stores better in the anchor locker, which means you can carry more chain
•
It does not bring up as much dirt on deck
•
It has a higher breaking load than the standard galvanized chain
•
It never needs to be re-galvanized
Not even the best stainless steel is 100% corrosion free. Under extreme conditions your Duplex
chain can also corrode if not treated well. The most critical factor is the temperature together
with saltwater. The Duplex 316AISI316LN chain is OK up to 34.5 degrees Celsius. Water
temperature more than 34.5 degrees is hard to find. But do not forget that the temperature in
anchor locker might be exceeding those temperatures in hot climates. A short flush with fresh
water will however take care of that problem.
Maintenance Chain:
Check the “Bitter end” rope regularly. The bitter end of the chain is connected to the bottom of
the chain locker and can easily be cut in case of an emergency. Turn the chain around after
some years. (Put the anchor in the other end) Regularly check the chain for cracks. Replace the
shackle between chain and anchor regularly. Flush the chain regularly with fresh water. This is
important both for galvanized and stainless steel chain if you leave the boat in hot climates for
extended periods.
Bow thruster
Your yacht may be fitted with an optional bow thruster, to help manoeuvring in harbours. It is operated
by foot buttons. Starboard button pushes the boat to starboard and vice versa. Avoid getting lines or
floating plastic drawn into the thruster tunnel. The manufacturers manual should be referred to
regarding maintenance and eventual limits for maximum operating time.
Dishwasher, washing machine and micro
If your boat is equipped with an optional dishwasher, washing machine or micro, please be aware that
those are only designed to be used in upright position. Do not use it when heeling. If you do so, those
will not work properly.
